The document reports the results of a titration experiment where increasing amounts of a sodium hydroxide (NaOH) base were added to an initial hydrochloric acid (HCl) solution. As more NaOH was added, the total volume, pH, and pOH values were measured. The pH increased from 1.3 to 12.08 as the amount of excess base increased from 0 to 25 ml. The pOH, which is the negative log of the hydroxide (OH-) concentration, correspondingly decreased from 12.7 to 1.92 over the course of the titration.
